    Can Volcanic Dust Suspended From Surface Soil and Deserts of Iceland Be Transferred to Central Balkan Similarly to African Dust (Sahara)? 
    Đorđević, Dragana; Tosic, Ivana; Sakan, Sanja; Petrović, Srđan; Đuričić-Milanković, Jelena; Finger, David C.; Dagsson-Waldhauserova, Pavla (Frontiers Media SA, 2019-07-03)
    In this work we use chemical fingerprints as characteristics ratios of specific crustal elements Ca/Al, Fe/Al, K/Al, Mg/Al, Mn/Al, Ca/Fe, and Mg/Fe to investigate the long-range transport of volcanic aerosols from Iceland. Volcanic dust enters the ...

    Climate variability in the past ∼19,000 yr in NE Tibetan Plateau inferred from biomarker and stable isotope records of Lake Donggi Cona 
    Saini, Jeetendra; Günther, Franziska; Aichner, Bernhard; Mischke, Steffen; Herzschuh, Ulrike; Zhang, Chengjun; Mäusbacher, Roland; Gleixner, Gerd (Elsevier BV, 2017-02)
    We investigated 4.84-m-long sediment record spanning over the Late Glacial and Holocene from Lake Donggi Cona to be able to reconstruct circulation pattern on the Tibetan Plateau (TP). Presently, Lake Donggi Cona is located at the boundaries of Westerlies ...

    High‐Temperature Deformation Behavior of Synthetic Polycrystalline Magnetite 
    Till, Jessica L; Rybacki, E.; Morales, L.F.G.; Naumann, M. (American Geophysical Union (AGU), 2019-03)
    We performed a series of deformation experiments on synthetic magnetite aggregates to characterize the high‐temperature rheological behavior of this mineral under nominally dry and hydrous conditions. Grain growth laws for magnetite were additionally ...

    Reactive transport of arsenic through basaltic porous media 
    Sigfusson, Bergur (University of Aberdeen, Aberdeen, 2009)
    This thesis studied the volcanic and geothermal source of arsenic (As) and its fate in shallow ground waters and upon entering the ocean by means of experimental and field measurements combined with geochemical modeling. Arsenic enters the atmosphere ...

    A study in blue : Secondary copper-rich minerals and their associated bacterial diversity in Icelandic lava tubes 
    Kopacz, Nina; Csuka, Joleen Mary; Baqué, Mickael; Iakubivskyi, Iaroslav; Guðlaugardóttir, Hrefna; Klarenberg, Ingeborg J.; Ahmed, Mahid; Zetterlind, Alexandra; Singh, Abhijeet; Kate, Inge L. ten; Hellebrand, Eric; Stockwell, Brent; Stefánsson, Árni B.; Vilhelmsson, Oddur; Neubeck, Anna; Schnürer, Anna; Geppert, Wolf (2022-05)
    Lava tubes on Mars hold exciting potential for the preservation of biosignatures, which may survive on geological timescales in these isolated, stable environments. To support the development of future astrobiological mission concepts, we turn to ...
